-
Severe vitamin D deficiency
- 25-OH Vitamin D: 9.6 ng/mL
- This is in the lab’s deficiency range, close to severe deficiency.
- Can contribute to fatigue, muscle/bone aches, weakness, and low mood in some people.
-
Vitamin B12 deficiency
- Vitamin B12: 143 pg/mL (normal 211-911)
- May cause tiredness, tingling/numbness in hands or feet, mouth ulcers, memory/concentration issues, or anemia. Your hemoglobin is currently normal, so there is no anemia at present.
-
Low TSH: possible thyroid overactivity
- TSH: 0.145 µIU/mL (low)
- Total T3: 95 ng/dL, normal
- Total T4: 9.05 µg/dL, normal
This pattern can indicate subclinical hyperthyroidism, meaning the thyroid-stimulating hormone is low but thyroid hormone levels are still within range. It can also occur temporarily during an illness, with certain medicines or supplements, or from a laboratory variation. It should be checked with repeat TSH plus free T4 and free T3. A low TSH is used to identify a possible thyrotoxic state, but free thyroid hormone testing and clinical assessment are needed to confirm it. Frameworks for Internal Medicine, p. 7836-7855.

Raised ESR: inflammation marker
- ESR: 50 mm/hour (reference for a man under 50: <15)
- ESR is a non-specific marker of inflammation. It can rise with recent infections, inflammatory/autoimmune conditions, tuberculosis, and many other causes. It does not diagnose a specific disease by itself.
- Given the high ESR, especially if you have fever, weight loss, night sweats, joint pain, cough, urinary symptoms, or persistent weakness, see a physician for examination and likely repeat ESR with CRP, and targeted tests based on symptoms.
-
Mild cholesterol abnormality
- LDL cholesterol: 115 mg/dL, mildly above the lab target
- HDL cholesterol: 37 mg/dL, low
- Total cholesterol and triglycerides are normal.
- This is not an emergency. Exercise, weight management if relevant, avoiding smoking, and a diet lower in saturated/trans fats can help. Your doctor can assess overall cardiovascular risk before considering medication.
Book a physician or endocrinology appointment within the next few days to address:
Seek urgent medical care if you have persistent high fever, severe weakness, breathing difficulty, chest pain, confusion, fainting, bleeding/rash, severe vomiting, black stools, or rapid/pounding heartbeat. A lab result alone cannot establish a final diagnosis, and results need to be interpreted with symptoms and examination, as
MedlinePlus explains.
